Absolute zero (or 0 degrees Kelvin) is not the same as 0 degrees Celsius. 0 degrees Kelvin is approximately -273 degrees Celsius. To maintain that
temperature would require more energy than would be produced.

ya its true i said celsius when i meant kelvin apologies for that mistype, will try and edit that out now

edit - success

yes it would be electricaly taxing to maintain such a cold temperature, and as someone mention a bit easier in space, but perhaps if scaled up enough
the build up of energy accumulated from such a device could eventualy overcome that limit,

Its called orbit man, you know satellites don't just float off into deep space right?

Phage- I can hardly ever think of any flaw in any of your thinking, despite my best efforts, your mind is a work of art. We capture helium and
condense it into liquid all the time here on earth, it isn't that hard to get it.

Do you think it would work more efficiently if say, I had the liquid tanks at a high altitude, say 7K up, like on Everest? Where nature would do the
work, or maybe antarctica? So that once the liquid helium was had, we might be able to keep it cold perpetually without add energy?

im pretty sure i can be a smart ass all i want, dont use insults like you just did, that much isnt permitted by the T&C of the site,

ALL scientiste of the time 100 years ago said flight was impossible, just the same as they say perpetual motion is impossible today,

the laws of physics have been broken many times already, they are only laws to the mind that accepts them as so,

quantum mechanics have already trumped them, so they continue even today to find away to tie them together without confliction and still struggle to
do so

dont just assume something is impossible becuase you are told so, think outside the box, think beyond what your told are the limits of possibility,
without that effort we never would have taken flight back then, it was that exact thinking that motivated them to try flight, and they did succeed in
flight

whats more we do not need to specify perpetual in a literal sense (wich is all that is claimed impossible) when only a practical sense will do.

magnets as example, they do not contain an endless amount of push, but their life spans far surpass your own so they 'practicaly' do

We have never thought flight was impossible, because other species can fly, it was just a matter of how we can achieve it, and the Wright brothers
figured it out. I don't think you quite understand these laws, perpetual motion is clearly impossible, it cannot exist. Also, If you are insulted by
phrases like "smart ass" then you need to get a grip, quite right you can be a smart ass all you want, but it doesn't make you right.

Perpetual motion is perpetual motion, I don't know what you mean by a "practical sense", if it's not literally perpetual motion, then it isn't
perpetual motion.

As the above poster pointed out, the first flight was 109 years ago, in 1903.

If the history of science has taught man anything, ikt is that nothing is impossible, just improbable. If we just assume things are not possible and
don't try, we would still be rubbing sticks together to make fire, and walking everywhere.

So no birds were flying more than 100 years ago....

!00 years ago man had been flying heavier than air aircraft for 9 years......

so my off the top of my head estimate was off by less then a decade hardly a point worth argueing, and ya birds have had flight, i need to specify man
made flight? thought a typical brain could easily interpret that properly, guess not,

not all of our man made objects in space are in orbit, yet they do not float away, their positions are maintained, yes it costs energy to do so, but
this is a dicussion about a theoretical device to produce energy.

also why not put this one into orbit anyway, the temperature couldnt be that drasticly different, should still achieve the aim of keeping some of
earths heat off of it.
